Post to an API is a great feature included with the Product Keys Delivery plugin 2.0.
We have released our newer version of Product Keys Delivery (PKD) for Magento 2.x which has many improvements but with a major feature called Post To An API. The Post to an API feature allows you to send your keys to 3rd party systems along with other required information using REST API protocol. You can use with any type of authentication that your 3rd party system requires such as API Key, Basic Auth or Bearer Token. You can flexibly use one of methods from POST, PUT or GET.
